If you don’t like your physician, find a new one

So, you’ve got diabetes. You’re trying to deal with it or you wouldn’t be here. You’ve got a heck of a lot of medical information to master.

Unless you have a good diabetes specialist physician on your team, you may not be getting optimal care. Below are some guidelines you may find helpful. The goal is to prevent diabetes complications. Many primary care physicians will not be up-to-date on the guidelines. Don’t hesitate to discuss them with your doctor. Nobody cares as much about your health as you do.

Annual Tests

The American Diabetes Association (ADA) recommends the following items be done yearly (except as noted) in non-pregnant adults with diabetes. (Incidentally, I don’t necessarily agree with all ADA guidelines.) The complete ADA guidelines are available on the Internet.

  • Lipid profile (every two years if results are fine and stable)
  • Comprehensive foot exam
  • Screening test for distal symmetric polyneuropathy: pinprick, vibration, monofilament pressure sense
  • Serum creatinine and estimate of glomerular filtration rate (MDRD equation)
  • Test for albumin in the urine, such as measurement of albumin-to-creatinine ratio in a random spot urine specimen
  • Comprehensive eye exam by an ophthalmologist or optometrist (if exam is normal, every two or three years is acceptable)
  • Hemoglobin A1c at least twice a year, but every three months if therapy has changed or glucose control is not at goal
  • Flu shots

Other Vaccinations, Weight Loss, Diabetic Diet, Prediabetes, Alcohol, Exercise, Etc.

Additionally, the 2013 ADA guidelines recommend:

  • Pneumococcal vaccination. “A one time re-vaccination is recommended for individuals >64 years of age previously immunized when they were <65 years of age if the vaccine was administered >5 years ago.” Also repeat the vaccination after five years for patients with nephrotic syndrome, chronic kidney disease, other immunocompromised states (poor ability to fight infection), or transplantation.
  • Hepatitis B vaccination to unvaccinated adults who are 19 through 59 years of age.
  • Weight loss for all overweight diabetics. “For weight loss, either low-carbohydrate, low-fat calorie-restricted, or Mediterranean diets may be effective in the short-term (up to two years).” For those on low-carb diets, monitor lipids, kidney function, and protein consumption, and adjust diabetic drugs as needed. The optimal macronutrient composition of weight loss diets has not been established. (Macronutrients are carbohydrates, proteins, and fats.)
  • “The mix of carbohydrate, protein, and fat may be adjusted to meet the metabolic goals and individual preferences of the person with diabetes.” “It must be clearly recognized that regardless of the macronutrient mix, total caloric intake must be appropriate to weight management goal.”
  • “A variety of dietary meal patterns are likely effective in managing diabetes including Mediterranean-style, plant-based (vegan or vegetarian), low-fat and lower-carbohydrate eating patterns.”
  • “Monitoring carbohydrate, whether by carbohydrate counting, choices, or experience-based estimation, remains a key strategy in achieving glycemic control.”
  • Limit alcohol to one (women) or two (men) drinks a day.
  • Limit saturated fat to less than seven percent of calories.
  • During the initial diabetic exam, screen for peripheral arterial disease (poor circulation). Strongly consider calculation of the ankle-brachial index for those over 50 years of age; consider it for younger patients if they have risk factors for poor circulation.
  • Those at risk for diabetes, including prediabetics, should aim for moderate weight loss (about seven percent of body weight) if overweight. Either low-carbohydrate, low-fat calorie-restricted, or Mediterranean diets may be effective in the short-term (up to 2 years). Also important is exercise: at least 150 minutes per week of moderate-intensity aerobic activity. “Individuals at risk for type 2 diabetes should be encouraged to achieve the U.S. Department of Agriculture (USDA) recommendation for dietary fiber (14 g fiber/1,000 kcal) and foods containing whole grains (one-half of grain intake).” Limit intake of sugar-sweetened beverages.
  • “Adults with diabetes should be advised to perform at least 150 min/week of moderate-intensity aerobic physical activity (50–70% of maximum heart rate), spread over at least 3 days/week with no more than two consecutive days without exercise. In the absence of contraindications, adults with type 2 diabetes should be encouraged to perform resistance training at least twice per week.”
  • Screening for coronary artery disease before an exercise program is depends on the physician judgment on a case-by-case basis. Routine screening is not recommended.

Olive, olive oil, and vinegar: classic Mediterranean foods

Obviously, some of my dietary recommendations conflict with ADA guidelines. The experts assembled by the ADA to compose guidelines were well-intentioned, intelligent, and hard-working. The guidelines are supported by 528 scientific journal references. I greatly appreciate the expert panel’s work. We’ve simply reached some different conclusions. By the same token, I’m sure the expert panel didn’t have unanimous agreement on all the final recommendations. I invite you to review the dietary guidelines yourself, discuss with your personal physician, then decide where you stand.

General Blood Glucose Treatment Goals

The ADA in 2013 suggests these therapeutic goals for non-pregnant adults:

  • Fasting blood glucoses: 70 to 130 mg/dl (3.9 to 7.2 mmol/l)
  • Peak glucoses one to two hours after start of meals: under 180 mg/dl (10 mmol/l)
  • Hemoglobin A1C: under 7%
  • Blood pressure: under 140/80 mmHg
  • LDL cholesterol: under 100 mg/dl (2.6 mmol/l). (In established cardiovascular disease: <70 mg/dl or 1.8 mmol/l may be a better goal.)
  • HDL cholesterol: over 40 mg/dl (1.0 mmol/l) for men and over 50 mg/dl (1.3 mmol/l) for women
  • Triglycerides: under 150 mg/dl (1.7 mmol/l)

The American Association of Clinical Endocrinologists (AACE) in 2011 proposed somewhat “tighter” blood sugar goals for non-pregnant adults:

  • Fasting blood glucoses: under 110 mg/dl (6.11 mmol/l)
  • Peak glucoses 2 hours after start of meals: under 140 mg/dl (7.78 mmol/l)
  • Hemoglobin A1C: 6.5% or less

The ADA reminds clinicians, and I’m sure the AACE guys agree, that diabetes control goals should be individualized, based on age and life expectancy of the patient, duration of diabetes, other diseases that are present, individual patient preferences, and whether the patient is able to easily recognize and deal with hypoglycemia. I agree completely.

The Problem With Diabetes Research

…according to an article at Medical News Today:

An analysis of diabetes trials worldwide has found they are not addressing key issues relating to the condition with almost two thirds focusing on drug therapy while only one in ten addresses prevention or behavioural therapies [which would include diet modification]. The research is published in Diabetologia, the journal of the European Association for the Study of Diabetes (EASD), and is by Dr Jennifer Green, Duke University Medical Center, Durham, NC, USA, and colleagues.

Moderate-Carb Diet No Better Than Standard High-Carb Diet In Gestational Diabetes

…according to a report at MedPageToday.

Women with gestational diabetes were randomized to either a 40% carb diet or 55% carb diet. The same numbers in each group ended up needing insulin therapy to control blood sugars.

Both groups ate the same amount of protein. The lower-carb group replaces some carbs with fat.

Pregnancy outcomes were similar in both groups.

Critics wonder if stricter carbohydrate restriction would have been more effective.

One More Study Shows Low-Carb Beats Low-Fat Diet for Weight Loss

low-carb diet, low-carb fruits, Steve Parker MD

Low-carb isn’t meat-only: You can eat these low-carb fruits

A low-carb diet was superior to a traditional low-fat weight loss diet, and without adverse effects on markers of systemic inflammation, according to a report at ScienceDaily. Some medical professionals are still hesitant to accept the validity of low-carb dieting, fearing that relatively high fat and protein content may promote inflammation, leading to atherosclerosis.  The study at hand should be reassuring in that regard.

Some quotes from ScienceDaily:

The researchers measured the participants’ blood levels for three common markers of inflammation — C-reactive protein, interleukin 6 and tumor necrosis factor-alpha — at the beginning and end of the study. They also measured body weight, body mass index (BMI) and total body and belly fat. At the start, both groups were similar in the various measures, including elevated levels of inflammation markers.

The participants on the low-carb diet lost more weight, on average, than those on the low-fat diet — 28 pounds versus 18 pounds [over the six month trial.

“In both groups, there was a significant drop in the levels of all three measures of inflammation,” says [Kerry] Stewart, indicating that a diet higher in fat and protein doesn’t interfere with the ability to lower inflammation, as long as you are losing weight.

Despite reading several online articles on this study, I can’t determine which low-carb diet was used, nor the level of carbohydrate restriction. Both diet groups exercised three times a week. I expect full details to be published in a scientific journal within a couple years. The research was done at Johns Hopkins University and was not funded by Atkins Nutritionals. U.S. taxpayers funded it.

If you’re looking for a low-carb diet, consider the Low-Carb Mediterranean Diet. Carb restriction starts at under 30 grams a day, but allows for increases over time as long as you’re making weight-loss progress. The typical American eats 250 to 300 grams of carbohydrate daily.

Which Diseases Do Vegetables and Fruits Prevent?

Potential answers are in the American Journal of Clinical Nutrition (2012).  I quote:

For hypertension, coronary heart disease, and stroke, there is convincing evidence that increasing the consumption of vegetables and fruit reduces the risk of disease. There is probable evidence that the risk of cancer in general is inversely associated with the consumption of vegetables and fruit. In addition, there is possible evidence that an increased consumption of vegetables and fruit may prevent body weight gain. As overweight is the most important risk factor for type 2 diabetes mellitus, an increased consumption of vegetables and fruit therefore might indirectly reduces the incidence of type 2 diabetes mellitus. Independent of overweight, there is probable evidence that there is no influence of increased consumption on the risk of type 2 diabetes mellitus. There is possible evidence that increasing the consumption of vegetables and fruit lowers the risk of certain eye diseases, dementia and the risk of osteoporosis. Likewise, current data on asthma, chronic obstructive pulmonary disease, and rheumatoid arthritis indicate that an increase in vegetable and fruit consumption may contribute to the prevention of these diseases. For inflammatory bowel disease, glaucoma, and diabetic retinopathy, there was insufficient evidence regarding an association with the consumption of vegetables and fruit.

It bothers me that vegetables and fruits are lumped together: they’re not the same.

All of my diets—Advanced MediterraneanLow-Carb Mediterranean, and Ketogenic Mediterranean—provide plenty of fruits and vegetables.

“Interval Walking” May Be Healthier Than Regular Walking For Diabetics

Not ready for this? Consider interval walking then.

Not ready for this? Consider interval walking then.

Compared to a regular continuous walking program, interval walking is superior for improving physical fitness, blood sugar control, and body composition (body mass and fatness), according to new research reported in Diabetes Care.

Study participants were type 2 diabetics. Training groups were prescribed five sessions per week (60 min/session) and were monitored with an accelerometer and a heart-rate monitor. Continuous walkers performed all training at moderate intensity, whereas interval walkers alternated 3-min repetitions at low and high intensity. Before and after the 4-month intervention, the following variables were measured: body composition, VO2max, and glycemic control (fasting glucose, hemoglobin A1C, oral glucose tolerance test, and continuous glucose monitoring).

I haven’t read the full report yet, but expect that the interval walkers walked as fast as they could for three minutes (4 mph?) then slowed down to a comfortable stroll (1–2 mph?) for three minutes, alternating thusly for 60 minutes.

This should easily do-able for nearly all type 2 diabetics.  The reported results are consistent with other studies of more vigorous and intimidating interval training.  The only caveat is that it was a small pilot study that may or may not be reproducible.

A Skeptical View of Invokana (canagliflozin), the New Diabetes Drug

Jenny Ruhl has a valuable post on the newest drug for type 2 diabetes: canagliflozin. A snippet:

If your doctor tries to put you on this drug, say no. Wait ten years, and search the literature then to see what scientists have found out about its real effects on patients before you try it.

Jenny says the pill will cost $8.77 (USD) per pill. Well worth a read.

Moderate Fruit Consumption May Not Sabotage Blood Sugar Control In Type 2 Diabetes

…according to an article in Nutrition Journal. These were newly diagnosed type 2 diabetics. This is interesting research because we’ve often assumed that the sugar in fruits would raise blood sugar too high, leading to recommendations to avoid fruits, or at least limit them to one piece daily.

The Well blog at the New York Times covered the story.  You’ll likely find the comments illuminating. Also see the Diabetes Self-Managment article. I’ll read the original research report when time allows.
